Conventional Hemodialysis vs. Short Daily Hemodialysis (6 Days / Week) and Mechanisms of Blood Pressure Control

Muscle sympathetic nerve activity measurement will be obtained using microneurography. Approximately 10-20% of microneurography recordings are not interpretable due to technical problems. For this reason, blood samples will be collected at the same time that the microneurography is to be done. These test will be done at 3 time points throughout the study.

bioimpedance measurement of extracellular fluid volume will be measured at the end of each 3 month period. This test will be done at 3 time points throughout the study.
